Poor weld detection system
Robo-navi-Bolt

Overview

Robo-navi-Bolt detects with a high accuracy the difference in length of the neck lower part and shape of the tip of the bolt right before welding. Also, it detects whether or not the workpiece is set correctly in the same way.
It prevents manufacturing defectively welded products.
It is a poor weld detection system developed for automated line using bolt feeder.
 
 

- SMK has acquired the intellectual property rights both inside and outside Japan.

Robo-navi-Bolt Slide Unit

Positioning is much easier

The replacement work can be done easily without time-consuming adjustment and centering work that occurs when replacing each part and electrode.

Holder has excellent cooling effect! Six sizes available.

Internal water-cooling system that directly cools the inside of the holder reduce abrasion and spatter adhesion caused by heat on the electrode part.
Slim and compact body without water jacket or intermediate adapter allows minimum interference with the workpieces.
 
We have 6 standard sizes for inner water-cooling holder.
Please contact us for other sizes.
 

Holder outer dia. Φ25 Φ32
Suitable for bolt M6・M8 M10
Holder lenghth 150㎜・200㎜・250㎜ 150㎜・200㎜・250㎜

 

Suitable for bolts with a length of 45 mm or less below the head.

Ceramics guide pipe specification

Ceramics guide pipe has high hardness and long service life. Because there is no electrocorrosion, nor abrasion. Also there is no adhesion of spatter and jamming of bolt.

Tact up effect

Vertical movement of the guide shaft enables high-speed movement of the workpiece, and to shorten tact time.

Air Blow system

Air blow system reduces spatter adhesion to bolts, guide pipes, and inside of the unit. Air cooling effect prevents heating of the electrode.
